GPM Racing 6061-T6 Alloy High Speed 30x10mm Cooling Fan 20000 Rpm for Arrma 1/16 Mini Kraton 3S Dsc 4x4 RTR Brushless Speed Truck (MAKM018FAN)

30x10mm high-speed cooling fan for Mini Kraton

This 30x10mm cooling fan is an RC-scale accessory designed for ARRMA Mini Kraton 3S platforms, built to manage motor temperature and support consistent brushless performance. The fan rotor is machined from 6061-T6 aluminium while the outer cover uses 7075-T6 alloy, offering a balance of light weight and structural durability appropriate for on-track and bashing use.

Electrical and mechanical details from the manufacturer specify a nominal speed of 20000 rpm ±20%, dual ball bearings, rated for 5V–9V operation with a typical current draw around 0.6A, and a direct connection option to the receiver power bus. Exceeding 9V risks burning the motor and must be avoided. The unit is suited to pair with the original GROM Motor Heatsink Type D 28mm diameter motors (ARA-2662).

Installation is straightforward for hobbyists familiar with small-scale hardware: the kit arrives pre-assembled, and final mounting uses supplied Grade 12.9 black flat head screws. Use a thread-locking compound on metal-to-metal fasteners to reduce the chance of loosening under vibration. Power can be sourced from an accessible receiver or a regulated switched BEC, observing the voltage limit noted above.

The fan’s role in tuning is practical and direct: it helps stabilise motor temps during repeated short runs or hard acceleration, which can maintain consistent ESC and motor behaviour without altering core gearing or motor timing settings. Monitor airflow clearance around the heatsink and avoid contact with wires or suspension components.

Compatible Models

• ARRMA 1/16 Mini Kraton 3S DSC 4X4 RTR Brushless Speed Truck-ARA2508S
• ARRMA 1/16 Mini Kraton 3S DSC 4X4 RTR Brushless Speed Truck-ARA2508

This cooling fan is a compact, metal-bodied option for ARRMA Mini Kraton 3S setups that need reliable airflow over the motor heatsink, install with the supplied hardware and observe the 9V voltage limit for safe operation.

Is this fan compatible with stock Mini Kraton 3S motors?

It is specified to fit with the GROM Motor Heatsink Type D 28mm diameter motors (ARA-2662) used on Mini Kraton 3S models.

How should I power the fan on my truck?

The fan runs on 5V–9V and can be powered from the receiver power rail or a regulated BEC; do not exceed 9V to avoid motor damage.

Are any special tools required for installation?

Standard small hex drivers are sufficient, and a thread-locker is recommended for the metal screws supplied to prevent loosening.

What maintenance does the fan need?

Periodic checks for debris, secure mounting, and proper voltage supply are recommended; replace if bearings develop excessive play or noise. Write Product Review Please sign in your account before you can write any review. Sign In Close
